                        Attributions for a particular neuron for the input or output
                        of this layer are computed using the argument neuron_selector
                        in the attribute method.
                        Currently, it is assumed that the inputs or the outputs
                        of the layer, depending on which one is used for
                        attribution, can only be a single tensor.
            multiply_by_inputs (bool, optional): Indicates whether to factor
                        model inputs' multiplier in the final attribution scores.
                        In the literature this is also known as local vs global
                        attribution. If inputs' multiplier isn't factored in
                        then that type of attribution method is also called local
                        attribution. If it is, then that type of attribution
                        method is called global.

                        are being multiplied by (inputs - baselines).

                        set to None.
